How to Make Breakfast Casserole – Easy & Hearty Brunch
Step 1: Preheat and Prep the Pan
Set your oven to 350°F and generously grease a 9×13-inch baking dish. This ensures the casserole comes out easily and gets those deliciously caramelized edges that nobody can resist.
Step 2: Sauté Onions and Sausage
Melt the butter in a large skillet over medium heat. Toss in the diced onions and sausage, breaking up the meat as you go. Cook until the sausage is fully browned and the onions are soft and fragrant. Don’t forget to drain off any excess grease to keep things light and tasty!
Step 3: Layer Biscuits and Sausage Mixture
Scatter the cut-up biscuit dough evenly over the base of your baking dish. Gently spread the hot sausage and onion mixture over top, so every bite gets a little bit of everything.
Step 4: Whisk Eggs, Milk, and Oregano
In a bowl, comfortably whisk together the eggs, whole milk, and oregano until totally smooth. Pour this mixture right over the sausage and biscuits. You’ll see it seep into all the nooks and crannies—this is where the magic happens!
Step 5: Top with Cheese and Warm Gravy
Sprinkle the shredded cheddar generously over everything, then drizzle the warm prepared country gravy across the top. Don’t be shy: the gravy is what makes this breakfast Casserole – Easy & Hearty Brunch so luscious and decadent.
Step 6: Bake to Golden Perfection
Slide your assembled casserole into the oven and bake for 30 to 40 minutes. You’re looking for a bubbling, cheese-crusted top and a just-set custard. Let it rest a few minutes before serving warm, so those layers hold together beautifully on every plate.
How to Serve Breakfast Casserole – Easy & Hearty Brunch

Garnishes
Finish your breakfast Casserole – Easy & Hearty Brunch with fresh chopped parsley, a dusting of black pepper, or a sprinkle of sliced chives. These little pops of color make it look as inviting as it tastes.
Side Dishes
Round out your brunch spread with fresh seasonal fruit, a crisp green salad, or even roasted potatoes if you want to turn decadence up to eleven. This casserole is rich, so balancing it out with juice or simple sides is a winning move.
Creative Ways to Present
Try baking the casserole in individual ramekins for a charming personal presentation, or cut it into neat squares for a casual, buffet-style brunch. Top each portion with an extra drizzle of warm gravy for maximum ooohs and ahhhs at the table.
Make Ahead and Storage
Storing Leftovers
Let any leftover breakfast Casserole – Easy & Hearty Brunch cool to room temperature, then wrap tightly or transfer to an airtight container. It will keep in the fridge for up to 3 days, and makes for an unbeatable breakfast or quick lunch later in the week.
Freezing
To freeze, simply portion the cooled casserole into airtight freezer containers or wrap the whole dish well in foil and plastic wrap. It’ll store beautifully for up to two months, so you can always have a batch ready for busy mornings or surprise guests.
Reheating
Reheat refrigerated slices in the oven at 325°F, covered, for 15 to 20 minutes until heated through. For single servings, the microwave works fine too—just cover and zap in short bursts so the biscuits don’t get rubbery.
FAQs
Can I use homemade biscuit dough instead of refrigerated?
Absolutely! If you have a go-to biscuit recipe, swap it in for an even more homemade touch. Just be sure to chop the dough into small pieces so it cooks evenly and soaks up all that delicious gravy goodness.
What kind of sausage works best?
I love classic pork breakfast sausage for maximum savory flavor, but turkey or chicken sausage works great too. Opt for your favorite, and feel free to use spicy or maple-flavored varieties for a unique twist on this breakfast Casserole – Easy & Hearty Brunch.
Can I add vegetables?
Definitely! Add-ins like sautéed bell peppers, mushrooms, or spinach are wonderful for an extra boost of flavor and nutrition. Just cook veggies beforehand so they don’t release too much liquid into the casserole.
Is it possible to assemble this casserole the night before?
Yes, and it makes brunch morning a breeze! Assemble the casserole as directed, cover, and refrigerate overnight. When you’re ready, let it sit at room temperature while the oven preheats, then bake as usual for a fresh, hot meal.
Can I double the recipe for a bigger group?
Of course! Make two 9×13-inch pans or use a larger baking dish if you’re feeding a crowd. Just keep an eye on the baking time—it may need to go a bit longer to ensure everything’s set and bubbling.
